it recomends roller rockers

but all the lunati spring for a sb are doubles with a damper and need machine work/pc seal to drop on

but...comp 901-16 cover all the sb cams they have

all the sb cams use the same lunati spring part #

and the comp 901 is within 10lbs of the spring rate and are cheaper,drop on with stock seals and no machine work

I did mine on the engine when I went to roller cam 60710

does look like a good one though

IMHO the 292/292 would be better and have a much better sound at idle

the 60710 is smooth like a stock cam
